The junction mannered null precast reinforced concrete cylinder component of the precast reinforced concrete cylinder component

摘要

PROBLEM TO BE SOLVED: To complete joining work quickly using a hardening filler having good characteristics in a joining method between a PCa column member and a PCa column/beam joint part block in which the hardening filler is injected into a joint space formed between an upper face of a column head of the PCa column member and a lower face of the PCa column/beam joint part block, and into a plurality of insertion holes for column main reinforcements of the PCa column/beam joint part block by injecting the hardening filler into the joint space.;SOLUTION: Cement mortar having fluidity is fed into the joint space 26 to allow it to flow from a lower end of each of the insertion holes 16 for the column main reinforcements so that it may fill the inside of the holes. Before the highest top end of the top ends of the hardening filler rising in the insertion holes reaches an upper end of the corresponding insertion hole, injection of the hardening filler is stopped to leave an unfilled part near the upper end of the insertion hole as a margin. The unfilled part is filled with the hardening filler injected from an upper end of each of the insertion hole.;COPYRIGHT: (C)2006,JPO&NCIPI
